Typical area of the reference plant community on alpine summits and shoulders.

Canopy cover and frequency of species in community 1.1.

Description

The reference state supports one community phase that is distinguished by the developed structure and dominance of the vegetation and the ecological function and stability of the community (fig. 4). The reference community phase is scrubland consisting of dwarf alpine shrubs and various lichens throughout.

This report provides baseline vegetation inventory data. Future data collection is needed to provide further information about existing plant communities. Common and scientific names are from the USDA PLANTS database. All community phases are characterized by the Alaska Vegetation Classification System (Viereck et al., 1992).
